I'd like to just wait and see what happens. They've shared exactly one scene together and it was fine. I'm hoping that if they do decide to explore that possible pairing, they let it develop slowly.

I agree that the maturity difference is rather large at the moment, but I think that could be easily rectified with some decent writing for Stephanie. I don't think her being a college student means she can't get involved with Philip. After all, Belle was a nursing student (for 5 minutes or so anyway). She was no more independent or mature than Stephanie is now. She just had a kid to make her seem older.
